HPSG analyses of non-configurationality

[Emily M. Bender]

Hello,

I'm looking for existing HPSG analyses of radical
non-configurationality, in particular, of languages 
with free word order including discontinuous NPs.
So far, I've only been able to turn up Donohue
and Sag's 1999 paper (reference below).

Thanks!
Emily
